PASTING-MACHINE Specification of Letters Patent.

Patented April 14, 1908.

T o all whom it may concern:

Be it known that I, JOSHUA R. HoUoHIN, a citizen of the United States,and a resident of Atlanta, in the county of Fulton and State of Georgia,have invented certain new and useful Improvements in Fasting-Machines,of which the following is a specification.

My invention relates to machines for applying paste, glue, gum, cementor other substances to paper articles, such as bags or sacks, and hasfor its object the improvement of devices of this character whereby thepaste or other substance is applied to the required place, such, forinstance, as the bottom fold of the bag, so as to secure the bestresults, and in such a way that it is not smeared over the outer side ofthe fold of the bag and the bag, as by the present method by externalpressure.

To this end my invention consists of two rollers between which the bagsare passed, one of which rollers is formed. hollow, so as to hold theaste, and provided with a line of openings or its egress, said rollerbeing connected with a hopper holding the paste by means of a tubularextension of the roller in which is mounted a screw or worm for feedingthe paste into the roller.

The details of the construction and operation of my invention will beexplained hereinafter, while the machine will be found illustrated inthe accompanying drawing, Which is a side view, partly in section, of myimproved pasting machine.

In the drawing 1 indicates a suitable base on which are mounted thestandards 2 and 3, in which are j ournaled rollers 4 and 5,simultaneously rotated by means of gear-pinions 6 and 7, respectively,keyed to or formed integral with the trunnions 8 of the rollers.

The upper roller 4 is formed hollow, as shown, and-provided with anumber of perforations 9, arranged longitudinally of the roller, whileinstead of a trunnion at one end it is provided with a tubular neck 10,journaled in j ournal-box 11.

The journal-box 11 is provided with an extension 12, on which is rigidlysecured hopper 13, provided at its lower end with an opening 14, andsurrounded by a stuffing-box 15 to receive the end of the tubular neck10.

The arrangement of parts by which the journal-boxes of the upper rollermay adjust themselves to varying thicknesses of material will be obviousto any one skilled in mechanics and a specific construction by whichthis may be effected is thought to be unnecessary.

To insure feed of the paste through the neck 10 to the interior ofroller 4, and to force it out of openings 9, I provide a screw or worm16 in said neck 10, which extends into the lower end of hopper 13, witha studshaft extending from its end through a journal-box at one side ofthe hopper, with a `pulley keyed thereto to receive a powerelt (notshown) for rotating the screw or worm.

It will be understood that the speed of the worm may be regulated toinsure feeding the proper amount of paste through openings 9 toadequately perform the work.

In operation, the hopper is filled with paste which is fed through neck10 by means of screw or worm 16 into roller 4, from whence it passesthrough openings 9 onto the bag or other article that passes between therollers 4 and 5.

It will be understood that the device above described may be operated asa separate machine by any suitable power or may be assembled with abag-making machine of any form to which it may be adapted and I do nottherefore confine myself to the construction shown and described exceptwhere the hereinafter claims are specifically limited.

It will also be understood that insteadvof one tubular neck and hopperand worm two may be provided, one at each end of roller 4.

Having thus described my invention, what I claim is` v 1. A pastingmachine comprising two complementary rolls provided with means toactuate them, one of said rolls being hollow and provided withperforations, said hollow roll having a tubular neck, a hopper suitablysecured and provided with an opening to receive the free end of saidtubular neck, and a worm mounted in said neck and hopper, substantiallyas shown and described.

2. A pasting machine comprising suitable standards, a roll j ournaled insaid standards, another roll journaled in boxes mounted in saidstandards, the last mentioned roll being hollow and provided withperforations, a tubular neck extending from said roll and forming one ofthe trunnions of the roll, a hopper secured to the journal box in whichis mounted said tubular neck, said hopper being provided with en openingto receive the free end of said tubular neck, a Worm mounted in saidtubular neck and said hopper, and a stud-shaft extending from said Worm,and a power-pulley keyed to said shaft, substan- 'tially as shown anddescribed.
